Phocine distemper virus

Phocine distemper virus (PDV) is a pathogenic for pinniped species such as seals. Signs include labored breathing, fever, and nervous symptoms. It was first identified in 1988 as the cause of death of 18,000 harbour seals along the northern European coast.

A PDV epidemic occurred again in 2002 along the North Sea coast resulted in the deaths of 21,700 seals. Numerous carnivorous mammal species in Canada have been found to have antibodies to PDV and CDV which shows that the virus spreads to new species.

PDV emerged suddenly and has led to implications that environmental changes as the cause. Pollutants have been identified as contributors by interfering with the ability of animals to mount a defense against infection.
